The drug tester 31 receives the drug falling through the final hopper 27 and inspects whether it is a normal drug corresponding to a single dose of the drug or a defective drug other than the normal drug. The drug inspector 31 includes a rotating body 32 , a camera 54 , a mirror 56 , a lower light 58 , a ring-shaped upper light 57 , and a guide cam 46 . ) is provided.

The rotating body 32 rotates about an axis CX parallel to the direction of gravity, that is, parallel to the Z axis, and the upper side of the rhombus and the panels 33 and 36 spaced parallel to each other. And, it is provided with a plurality of medicament carriers (carrier) (41) interposed between the upper panel (33) and the lower panel (36). A plurality of medicament carriers 41 are arranged at equiangular intervals at positions off the axis CX. In the illustrated embodiment, the four medicament carriers 41 are arranged at intervals of 90 ° about the axis line (CX), but the three medicament carriers 41 are arranged at intervals of 120 ° about the axis line (CX). may be

As the rotating body 32 rotates, each medicament carrier 41 circulates while sequentially passing through the medicament input position, the medicament inspection position, the medicament dispensing position, and the standby position. 4, the rotating body 32 rotates counterclockwise, and the medicament carrier 41 having the largest Y-axis coordinate value among the four medicament carriers 41 is a medicament carrier located at the medicament input position. And, the position where the drug input position is rotated by 90° counterclockwise around the axis (CX) is the drug inspection position, and the position where the drug input position is rotated by 180° counterclockwise around the axis (CX) is a position is the drug delivery location. Moreover, the position where the chemical|medical agent injection position rotated 270 degrees counterclockwise around the said axis line CX is a standby position.

The medicament input position is a position in which the medicament falling from the final hopper 27 (see FIG. 2) to the medicament tester 31 is accommodated in the medicament carrier 41. The drug inspection position is a position where it is inspected whether the drug accommodated in the drug carrier 41 at the drug injection position is a normal drug corresponding to a single dose of a drug according to a prescription, or a defective drug other than a normal drug. The medicament drop position is a position where the medicament tested at the medicament inspection position is discharged from the medicament carrier 41 and dropped under the rotating body 32 . The standby position is a position in which the medicament is released from the medicament dispensing position and the medicament carrier 41 that is not filled therein waits before entering the medicament injection position again. On the other hand, unlike the embodiment shown in Figure 2, in the case of an embodiment provided with only three medicament carriers spaced apart at equal angular intervals on the rotating body, the standby position is not provided.

Each medicament carrier 41 is movable between a first position between the upper panel 33 and the lower panel 36 and a second position closer to the axis CX than the first position. As shown in Figure 4, in the drug input position, the drug test position, and the standby position, the medicament carrier 41 is located in the first position, and in the medicament dispensing position, the medicament carrier 41 is located in the second position. In FIG. 4 , the medicament carrier 41 located in the first position is illustrated by a solid line, and the medicament carrier 41 located in the second position is illustrated by a dotted line. Each medicament carrier 41 is provided with an inner surface 42 that forms a closed curve so that the upper and lower sides are provided with an upper opening (opening) and an inner space formed with a lower opening. In the embodiment of FIG. 4 , the planar shape of the inner surface 42 is circular. Each medicament carrier 41 has a constant length in a direction parallel to the Z axis.

The upper panel 33 has an upper panel through-hole 34 overlapping the upper opening of the medicament carrier 41 located in the first position, and the lower panel 36 has the medicament carrier 41 located in the second position. A lower panel through-hole 73 overlapping the lower opening of the . In the embodiment of Figure 4, the size of the inner diameter of the upper panel through hole 34 and the lower panel through hole 73 is equal to the size of the inner diameter of the inner surface 42 of the medicament carrier 41. However, Figure 4 is exemplary, and the shape of the upper panel through hole 34 and the lower panel through hole 73 and the planar shape or size of the inner surface 42 of the medicament carrier 41 may be different from each other.

The upper panel 33 is formed with a guide through-hole 35 extending in a radial direction about the axis CX. The guide through-hole 35 is provided with a number corresponding to the number of the drug carrier (41). Each medicament carrier 41 is provided with a guide projection 44 corresponding to the plurality of guide through-holes (35) one-to-one. The guide protrusion 44 penetrates the guide through hole 35 and protrudes upward of the upper panel 33 . When the guide protrusion 44 is positioned at one end of the guide through hole 35 furthest from the axis CX, the medicament carrier 41 is positioned in the first position. Conversely, when the guide projection 44 is located at the other end of the guide through hole 35 closest to the axis CX, the medicament carrier 41 is located in the second position.

Since the drug dropped from the final hopper 27 (see FIG. 2) falls to the position of the upper panel through hole 34 of the drug input position, it passes through the upper panel through hole 34 and the inner surface of the medicament carrier 41 It is filled in the inner space defined by (42). In this position, the lower opening of the medicament carrier 41 is closed by the lower panel 36 , so that the medicament is confined in the space inside the medicament carrier 41 and does not drop under it. Since the medicament carrier 41 is located in the first position even in the medicament inspection position, the medicament is confined in the internal space of the medicament carrier 41 and is not dropped below it.

However, in the medicament dispensing position, the medicament carrier 41 moves to a second position, in which the lower opening of the medicament carrier 41 overlaps the lower panel aperture 73 and opens downward. Accordingly, the drug trapped in the inner space of the medicament carrier 41 is dropped under the rotating body 32 through the lower panel through-hole 73 .

The guide cam 46 is separated from the rotating body 32 and does not rotate, and is disposed to overlap the drug drop position on the upper side of the rotating body 32 . The guide cam 46 has first and second curved paths 47 , 48 for guiding the medicament carrier 41 by interfering with the guide protrusion 44 of the medicament carrier 41 . The first curved path 47 is a curved path for guiding the medicament carrier 41 moving from the medicament inspection position to the medicament dispensing position by the rotation of the rotating body 32 from the first position to the second position, the second curve The path 48 is a curved path for guiding the medicament carrier 41 moving to the standby position through the medicament dispensing position by the rotation of the rotating body 32 from the second position to the first position.

In other words, the drug carrier 41 located in the first position in the drug inspection position rotates together as the rotating body 32 rotates and moves to the drug dispensing position, the upper end of the guide protrusion 44 is a ridge. It is blocked by the extended first curved path (47) and is not directed to the first position of the medicament dispensing position, but moves to the second position of the medicament dispensing position along the first curved path (47). In this way, the drug carrier 41 located at the second position in the drug delivery position rotates with the rotation body 32 as the rotation body 32 rotates and moves to the standby position. 44 is blocked by the second curved path 48 extending like a ridge, so that it is gradually moved to the first position along the second curved path 48 .

On the other hand, the means for moving the medicament cassette 41 from the first position to the second position in the medicament dispensing position is not limited to the guide cam 46, for example, using a spring from the first position to the second It is also possible to pressurize the medicament carrier into position. However, the means using the spring has a more complicated structure and takes up more space than the guide cam 46 shown in FIG. can Reference numeral '51' denotes a motor 51 providing power to rotate the rotating body 32, and reference numeral '52' denotes the rotation speed of the motor 51 so that the rotation speed of the rotating body 32 is precisely controlled. It is a speed reducer that slows down

In order to inspect whether the medicament accommodated in the medicament carrier 41 is the normal medicament or the bad medicament, the camera 54 images the inside of the medicament carrier 41 located at the first position in the medicament inspection position. The mirror 56 is separated from the rotating body 32 and does not rotate, and is disposed to overlap the drug test position on the upper side of the rotating body 32 . The mirror 56 refracts the path of light emitted from the drug inspection position toward the camera 54 so that the camera 54 is disposed at a position that does not overlap the rotation body 32 and up and down. . Accordingly, the camera 54 can be disposed by avoiding the hoppers 26 and 27, and thus can advantageously act in designing the blister packing device 20 of the medicament to be compact.

The photo file (file) of the drug taken by the camera 54 is transmitted to the controller 29, the controller 29 examines the photo file of the drug and the drug carrier 41 located at the drug inspection position It is determined whether the drug accommodated in the above is the normal drug or the bad drug. The lower light 58 is separated from the rotating body 32 and does not rotate, and is disposed to overlap the drug test position on the lower side of the rotating body 32 . The annular upper light 57 is separated from the rotating body 32 and does not rotate, and is disposed to overlap the drug test position on the upper side of the rotating body 32 and under the mirror 56 . The lower light 58 and the annular upper light 57 project light to the medication carrier 41 located in the first position from the medication inspection position so that a brighter and clearer picture file of the medication is captured by the camera 54 do.

The lower panel 36 has the lower panel 36 so that the light projected from the lower light 58 passes through the lower panel 36 and is irradiated to the medicament carrier 41 located at the first position in the medicament inspection position. A transparent window 38 is provided which is detachably attached to the . The removable transparent window 38 is disposed to overlap with the medicament carrier 41, and is provided to correspond to a plurality of medicament carriers 41 and one-to-one. In other words, the removable transparent window 38 is mounted on the lower panel 36 by pushing it from the outer peripheral surface of the lower panel 36 toward the axis CX, and pulling it out in a radial direction away from the axis CX. It is detachable from the lower panel 36 . The lower panel through hole 73 may be formed in the removable transparent window 38 .

When the medicament inspector 31 is used for a long time, the medicament carrier 41 slides on the transparent window 38 and repeatedly moves in the direction toward the axis CX and in the opposite direction. Accordingly, a lot of scratches may be generated on the transparent window 38 . If a lot of scratches occur on the transparent window 38 as described above, the shape or number of drugs is unclear in the photo file of the drug taken by the camera 54, and this causes the controller 29 to convert the normal drug into a bad drug or bad. A test error of determining that the drug is a normal drug may occur. Accordingly, the transparent window 38 with a large number of scratches can be removed from the lower panel 36 and replaced with a new product without scratches to be mounted on the lower panel 36 .

The medicament diverter 60 includes a hopper 61, a bad medicament receiving container 63, a normal medicament guide channel 62, and a directional valve 64 after the medicament inspection. . The drug dropped down from the drug tester 31 passes through the hopper 61 after the drug test and is collected. After the drug test, the upper opening of the hopper 61 is aligned with the lower panel through hole 73 provided at the drug drop position of the rotating body 32 . Defective drug container 63 is a container in which the bad drug is dropped and accommodated when the drug that has passed through the hopper 61 after the drug test is a bad drug, for example, it may be a cup-shaped container with a handle. have. Among the drugs accommodated in the defective drug accommodating container 63, the available drugs may be transferred to the drug cassette 23 in which the same kind of drug is accommodated.

The normal drug guide channel 62 is a channel for guiding the normal drug to fall to the distribution block 72 side when the drug that has passed through the hopper 61 after the drug test is a normal drug. The direction switching valve 64 is dropped from the drug tester 31 and guides the drug collected in the hopper 61 after the drug test to one of the defective drug accommodating container 63 and the normal drug guide channel 62 . In other words, when the controller 29 determines that the drug imaged by the camera 54 at the drug test position is a normal drug corresponding to a single dose, the imaged drug is dropped from the drug drop position, and the drug The controller 29 controls the operation of the directional valve 64 so that the directional valve 64 guides the medicament to the normal medicament guide channel 62 at the time of passing through the hopper 61 after inspection. do. In addition, if the controller 29 determines that the drug imaged by the camera 54 at the drug inspection position is a defective drug that does not correspond to a single dose, the imaged drug is dropped from the drug drop position and the drug The controller 29 controls the operation of the directional valve 64 so that the directional selector valve 64 guides the medicament to the defective medicament container 63 at the time of passing through the hopper 61 after inspection. do.

The distribution block 72 is a block of a substantially rectangular parallelepiped shape having a constant thickness, which is disposed under the drug direction diverter 60, and is opened in the vertical direction, that is, a plurality of pockets penetrating the distribution block 72 in the thickness direction. A corresponding hole 73 is formed. The plurality of pocket-corresponding through-holes 73 correspond to the plurality of medicament pockets 6 of the blister sheet 2 on a one-to-one basis. In other words, the plurality of pocket-corresponding through-holes 73 of the distribution block 72 shown in FIG. 5 are arranged in a matrix of 7 rows and 4 columns like the plurality of drug pockets 6, and between the adjacent pocket-corresponding through-holes 73. The spacing of is also equal to the spacing between adjacent drug pockets (6).

The distribution block 72 is rapidly movable in a horizontal direction orthogonal to a direction in which gravity acts, that is, a direction parallel to the X axis and a direction parallel to the Y axis. A mechanism for moving the distribution block 72 in the horizontal direction is not particularly limited. The shutter 75 openably closes the openings at the lower ends of the plurality of pocket-corresponding through holes 73 formed in the distribution block 72 . The shape of the shutter 75 is a flat plate shape, and the shutter 75 is disposed below the distribution block 72 . Specifically, the shape of the shutter 75 has a length substantially equal to the length of the distribution block 72 in a direction parallel to the X axis, and is larger than the length of the distribution block 72 in a direction parallel to the Y axis. It may be a rectangular plate having a length.

The shutter 75 has a closed position for closing the openings at the lower ends of all the pocket-corresponding through-holes 73 of the distribution block 72 and opening the lower ends of all the pocket-corresponding through-holes 73 of the distribution block 72 . movable between open positions. The shutter 75 may move in a direction parallel to the Y-axis. 3 and 5 the shutter 75 is located in the closed position. However, when the shutter 75 moves in a direction parallel to the Y-axis and is positioned in the open position, the shutter 75 does not overlap the distribution block 72 in the vertical direction, so that all the pocket-corresponding through holes ( 73) The opening at the bottom is open.

The shutter drive motor 77 provides power for the shutter 75 to reciprocate between the open position and the closed position. A distribution block holder 70 fixedly supports the distribution block 72 and the shutter driving motor 77, and supports the shutter 75 reciprocally between the open position and the closed position. A holder support frame (frame) 66 fixedly disposed below the drug tester 31 movably supports the distribution block holder 70 in a horizontal direction parallel to the X-axis and the Y-axis. Reference numeral '67' denotes a Y-direction driving motor that provides power to move the distribution block holder 70 in a direction parallel to the Y-axis. An X-direction driving motor that provides power to move the distribution block holder 70 in a direction parallel to the X-axis is omitted from the drawing.

In a state in which the openings at the lower ends of the plurality of pocket-corresponding through holes 73 of the distribution block 72 are closed by the shutter 75 located in the closed position, the normal drug is intermittently supplied from the lower end of the normal drug guide channel 62 by one dose. The normal medicine is sequentially introduced and accommodated in the closed plurality of pocket-corresponding through-holes 73 by falling to. In other words, when the first dose of the normal drug falls from the lower end of the normal drug guide channel 62, the pocket-corresponding through hole 73 at the position of one row and one column is connected to the lower end of the normal drug guide channel 62. It is positioned to be aligned in the vertical direction, and when the second dose of the normal drug falls from the bottom of the normal drug guide channel 62, the distribution block 72 is slightly moved in the direction parallel to the X-axis to move 1 row 2 columns The pocket corresponding through hole 73 of the position is positioned to be aligned with the lower end of the normal medicament guide channel 62 in the vertical direction. For example, in this way, the normal medicine for one dose is sequentially filled from the pocket-corresponding through-hole 73 at the position of the first row, 1st column to the pocket-corresponding through-hole 73 at the position of the 7th row and 4th column sequentially. However, according to the prescription input to the blister packing device 20 of the medicine, the medicine may not be injected into some of the pocket-corresponding through-holes 73 among the plurality of pocket-corresponding through-holes 73 .

When the plurality of pocket-corresponding through holes 73 are filled with a normal drug according to the prescription, the blister sheet 2 moves downward of the drug dispensing unit 30 while being supported on the blister sheet tray 101; The distribution block 72 moves in the horizontal direction to be aligned up and down. At this time, all the pocket-corresponding through-holes 73 of the distribution block 72 and all the medicine pockets 6 of the blister sheet 2 are aligned in a one-to-one correspondence. In this way, in a state in which the distribution block 72 is positioned on the blister sheet 2 to be aligned, the shutter 75 is moved to the open position so that the openings at the bottom of the plurality of pocket-corresponding through holes 73 that were closed by the shutter 75 are closed. is opened, whereby the normal medicament accommodated in the plurality of pocket-corresponding through-holes 73 falls into the plurality of medicament pockets 6 at the same time and is accommodated. The blister sheet tray 101 supporting the blister sheet 2 filled with the normal medicine according to the prescription in the plurality of medicine pockets 6 moves to the lower point of the cover attaching unit 120 and stops.

According to a preferred embodiment of the present invention, the shutter 75 is in the closed state, that is, the time when the drug starts to be filled in the dispensing block 72 with the shutter 75 in the closed position and the shutter 75 ) is opened, that is, between the time when the shutter 75 is moved to the open position, the blister sheet 2 is transferred to the distribution block 72 by the blister sheet conveying unit 100 (see FIG. 2 ). ) is transferred to a position aligned with the distribution block 72 below.

In other words, the blister sheet 2 moves from the blister sheet supply unit 110 to the bottom of the medicament dispensing unit 30 after the normal medicament is filled in the dispensing block 72 and preparation for dropping the medicament is completed. Rather than doing this, the blister sheet 2 can receive the falling medicine from the distribution block 72 in advance before the preparation for dropping the medicine from the distribution block 72 to the blister sheet 2 is completed. It is configured to move to and wait. Due to this, the time interval between the time when the medicament is filled in the distribution block 72 and the time when the shutter 75 is opened is reduced, resulting in the productivity of the blister packing operation through the blister packing device 20 of the medicament. This is improved.

The medicine dispensing unit 30 for the blister pack described above determines whether or not the medicine falling from the medicine supply unit 22 is normal based on the prescription, and if it is a normal medicine, a plurality of medicine pockets ( 6) automatically performs the task of distributing and dropping the dose at a time. Therefore, the speed of the operation of blister packing the medicament is improved. In addition, in the medicine dispensing unit 30 for the blister pack, the normal medicine of one dose falls 3 times or more every time the rotating body 32 rotates once. Accordingly, the speed of the operation of blister packing the medicament is further improved.

And, the blister packing device 20 of the above-described medicine, the blister sheet 2 between the time when the medicine starts to be filled in the distribution block 72 and the time when the shutter 75 is opened, the distribution block ( 72) is moved to the position aligned below. In other words, the operation of the blister sheet supply unit 110 and the operation of the blister sheet conveying unit 100 and the operation of the medicine dispensing unit 30 for the blister pack may proceed while overlapping time, so The speed of the packing operation is further improved.

Although the present invention has been described with reference to the embodiments shown in the drawings, which are merely exemplary, those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Accordingly, the true scope of protection of the present invention should be defined only by the appended claims.
